Phase I/II trial to study the effectiveness of SGN-00101 in preventing anal cancer in HIV-positive patients who have high-grade anal neoplasia. Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. SGN-00101 may be effective in preventing anal cancer.

II. Determine clinical response and histologic/cytologic regression in patients treated with this drug.

III. Determine immune response in patients treated with this drug. IV. Determine the effect of this drug on HIV viral load and CD4 level in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive SGN-00101 subcutaneously once on weeks 0, 4, and 8. Treatment continues in the absence of disease progression or unacceptable toxicity.

Cohorts of 5-6 patients receive escalating doses of SGN-00101 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 1 of 6 patients experience dose-limiting toxicity.
